5. The lending library may reasonably stipulate: (a) That the entire cost of the service shall be met by the borrowing library, and may look to this library alone as responsible both for the safety and prompt return of the material and for the replacement of the material if lost or damaged, and (b) it may reasonably include as part of the expense: (1) packing; (2) carriage; (3) insurance; (4) the fraction, if estimable, which the particular loan should bear of the expense of administering the service. (c) As to the duration of the loan: that it shall not exceed the period of its local loans, with an allowance added for the transit both ways; and the lender may reasonably couple with this a right of summary recall. It may also impose penalties for delays in returning material, or for carelessness in its use or in repacking. It may of course reserve the right to decline further loans to a library which has shown indifference in these regards, or whose applications have been incessantly frivolous. (d) It may of course limit the number of volumes lent to any one library or for the use of any one investigator at any one time. (e) It may, without prejudicing applications from other institutions, deny the application of any particular library, because of lack of assurance as to the safety or intelligent use of the material if lent. Its decisions in this regard resting often upon the impressions of a general experience, ought to be unembarrassed. It should not therefore be called upon to explain them. HERBERT PUTNAM. II =A statement of general policy in regard to inter-library loans= The primary purpose of inter-library loans is the promotion of scholarship by placing books not commonly accessible and not in use in one library, temporarily at the service of a scholar who has access to some other library. It should not be allowed to interfere with the reasonable and customary use of books by home readers, and the extent to which sending can be carried depends on the local conditions of the lending library, the importance of the service to be rendered, the character of the books desired, the distance to which they are to be sent, and a number of other circumstances. The larger university libraries, having large numbers of professors, advanced students and other professional scholars immediately dependent on them, may find it necessary to restrict the scope of their loans in justice to their local constituency, while others may rightly extend the system beyond the limits indicated, so as to meet the wants of readers in public libraries, teachers in high schools, and others.
